Which of the following statements best describes "carbon fertilisation"?
- A.Increased plant growth due to increased concentration of carbon dioxide in the atmosphere
- B.Increased temperature of Earth due to increased concentration of carbon dioxide in the atmosphere
- C.Increased acidity of oceans as a result of increased concentration of carbon dioxide in the atmosphere
- D.Adaptation of all living beings on Earth to the climate change brought about by the increased concentration of carbon dioxide in the atmosphere
▶ Answer & Explanation
Correct answer: A. Increased plant growth due to increased concentration of carbon dioxide in the atmosphere
Carbon fertilisation refers to the phenomenon where elevated levels of atmospheric carbon dioxide stimulate photosynthesis in plants, leading to enhanced growth and biomass production. While increased CO2 is a primary driver of global warming (option B) and ocean acidification (option C), and while adaptation to climate change is a consequence (option D), carbon fertilisation specifically denotes the positive effect on plant productivity.
